8.5 Cooling Requirements
Ping200Sr is designed to meet all applicable TSO requirements without
forced-air cooling.
Attention should, however, be given to the incorporation of cooling
provisions to limit the maximum operating temperature if Ping200Sr is
installed in close proximity to other Avionics. The reliability of equipment
operating in close proximity in an avionics bay can be degraded if adequate
cooling is not provided.
8.6 Antenna Installation
The following considerations should be taken into account when siting the
antenna.
•
The antenna should be mounted in a vertical position when the
aircraft is in level flight.
•
Avoid mounting the antenna within 1 meter of the ADF sense antenna
or any COMM antenna and 2 meters from the transponder to the
DME antenna.
•
Where practical, plan the antenna location to keep the cable lengths
as short as possible and avoid sharp bends in the cable to minimize
the Voltage Standing Wave Ratio (VSWR).
Electrical connection to the antenna should be protected to avoid loss of
efficiency due to exposure to liquids and moisture. All Antenna feeders
shall be installed in such a way that a minimum of RF energy is radiated
inside the aircraft.
